  • Closed loop active cancellation technique (ACT)-based RF power amplifier linearization architecture
    Patent number: 6452446
    Abstract: A closed loop, active cancellation technique (ACT)-based RF power amplifier linearization architecture injects a pilot tone as a ‘pseudo distortion’ signal into signal paths through first and second matched RF amplifiers, and a set of power minimization loops are closed around the RF amplifier pair. The power minimizing control loops control a set of vector modulators such that both the injected pilot tone and intermodulation distortion products are canceled, while RF carrier components constructively sum in the composite output of the two RF amplifiers.
    Type: Grant
    Filed: December 20, 2001
    Date of Patent: September 17, 2002
    Assignee: Spectrian Corporation
